Description

Aaabrenner warp knitted web

In d <? ~ ": Erei have long been textile fabrics known with A ^ v ^ eanereffekt (etched pattern)

The etching patterns are achieved by using core yarns or mixed yarns made from an etchable, mostly cellulosic fiber and a non-etchable, mostly synthetic fiber. In the case of woven fabrics, there is also the option of using both types of fibers in repeats "Outside the weaving mill there are also" burnouts ¹¹ known that are produced using the Malimo technique. Here a non-etchable thread is used as the sewing thread and an etchable material is used as the weft thread. With this technique, however, it is necessary to use partially non-etchable threads in the warp and weft directions, so that the required stability of the Malimo knitted fabric is guaranteed.

It is also known to use core yarns made from warp knitted fabrics to achieve a burn-out product consist of an endless, non-etchable filament yarn with cellulosic fibers, e.g. cotton or rayon is wound.

All of these known techniques have the disadvantage that £ Special core or mixed yarns must be used or that can be etched for stability in the warp and weft directions Threads must be used.

The innovation according to the invention is that a burn-out warp knitted web instead of core or mixed yarns are made from simple yarns, i.e. cellulosic and synthetic yarns in their pure form. For this purpose, t.B. following construction on a Raschel machine developed with four guide rails and a division of 24 gauge (see sample):

—— 2 ——

L ₁ Material: Polyester d'tex 100 Laying: fringe

Material: Polyester d'tex 100 Laying: weft

Material: Zellwoll-Garn Nm 18 and Nm 15/2 as well as

according to sample Trevira Nm 20/2 Laying: standing fiden

L ^ material: polyester d * tex 100 Laying: shot.

It is easily possible to achieve the stability required for the respective desired purpose (e.g. decoration fabric, bodice fabric, outerwear fabric, etc.), to reach.

The innovation has compared to the previous burn-out warp knitted Considerable technical advantages · So you can easily use simple pure yarns instead of the exueblich more expensive ones core yarns to be produced are employed. In addition, a considerable stability is achieved in the case of threads in warp thread. The finished burnout product shows also a clear difference between the burned-out and the non-burned-out areas. Another advantage is that the knitted web does not have a pronounced mason structure but villig in its external appearance resembles a fabric.

Of course, the construction specified above is only an example that can be easily modified in terms of layout without any further effort. For example, it would be possible for the guide rails L ₂ and / and L ^ to be in place of "weft?"

Also could be etchable and not instead of the ones we applied etchable yarns, polyester and cellular wool, also other technically usable combinations, e.g. polyester / cotton, trlacetate / Viscose, etc. can be used.

Claims (1)

Claim to protection 1.) Ausbremer warp knitted web, characterized in that that they are made from a basic knitted fabric made of simple, pure, non-etchable yarns as well as standing threads made of pure, consists of simple, etchable yarns, with the standing threads partially etched out of the knitted fabric in a pattern 703556 * 21.1.71
